Sansevieria plant named ‘OSV Sans 010’

ABSTRACT

A new and distinct Sansevieria plant having leaves with a light grey-green central portion and a prominent grey-yellow lateral border.

Botanical classification: Sansevieria sp.

Varietal denomination: ‘OSV Sans 010’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct variety of Sansevieria plant having the varietal name of ‘OSV Sans 010’. The new variety was discovered and selected by the breeder in a cultivated production bed environment in Williamsburg, Costa Rica as a naturally occurring mutation amongst a population of unpatented and unnamed Sansevieria plants. As such, the exact parentage is unknown. The new variety was selected and first asexually reproduced by rhizome cuttings in Williamsburg, Costa Rica. ‘OSV Sans 010’ has been trial and field tested and has been found to retain its distinctive characteristics and remain true to type through successive propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.

When compared to Sansevieria variety named ‘OSV Sans 002’ (U.S. Plant patent application Ser. No. 17/495,392), the new variety exhibits a similar rosette leaf formation with leaves growing upward and then curving outward. However, ‘OSV Sans 010’ has a light greyish green colored central leaf area with light yellow colored margins and ‘OSV Sans 002’ has vertical leaf striping and faint horizontal lines along the leaf center with consistent green margins. Also, ‘OSV Sans 010’ has longer and narrower leaves than ‘OSV Sans 002’. Further, the following characteristics distinguish ‘OSV Sans 010’ from other Sansevieria varieties known to the breeder:

-   -   Rosette leaf formation;     -   Prominent leaf margins;     -   Leaves grow upward and then curve outward; and     -   Narrow and long leaves.

DESCRIPTION OF THE DRAWING

The accompanying photographic drawing taken at approximately 18 weeks of age for the central plant and slightly varying ages for the other shown plants of the same variety, which illustrates the new variety, with the colors being as nearly true as is possible with color illustrations of this type.

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of the new variety at approximately 1 year of age. The data which defines these characteristics was collected in a greenhouse in September of 2021 in Winter Garden, Fla. Plants of the new variety were grown under 2,000 foot candles of artificial light in 15 cm pots in a climate-controlled greenhouse in Winter Garden, Fla. having 86% relative humidity and an average temperature of 28° C. Color references are primarily to the Munsell Plant Tissue Color Book, 2019 publication, except where general color terms are used.
